Development Update: Feb. 1, 2019

Marriott International Headquarters

February 1, 2019:

As the community may be aware, leaks have been discovered in a WSSC water line adjacent to the Marriott Headquarters construction project. This leak, which is unrelated to the construction project, is causing water to flow onto the adjacent sidewalk and along the east side of Woodmont Avenue toward Bethesda Place resulting in unsafe conditions due to the ongoing extreme cold weather. This leak was identified last Friday morning and WSSC was immediately notified by general contractor Hensel Phelps. In order to minimize the impacts to the adjacent businesses and community, WSSC has scheduled the repairs for late Sunday evening, February 3, as the work will require a temporary service outage. WSSC has committed to maintaining and salting the sidewalks until the line is repaired.

Until the repair is completed, the sidewalks in the immediate areas have been closed along the east side of Woodmont Avenue between Norfolk and Old Georgetown Road. Please be vigilant and pay close attention to the signage directing pedestrians use the opposite sidewalk until repairs can be completed. During this time, we ask for your patience and thank you for your understanding, and we apologize for any inconvenience this may cause. Our number one priority is pedestrian safety in and around the construction site.



Monthly construction updates

The developers and general contractor hold monthly construction updates for the general public. These updates are generally scheduled for the first Tuesday of each month and take place in downtown Bethesda at the Montgomery County Regional Service Center, on the second floor in rooms A and B, located at 4805 Edgemoor Lane, Bethesda, MD 20814.

The next update will take place this Tuesday, February 5th at 6:00 p.m.
